Through my long immersion as a student-practitioner in the Tibetan Buddhist knowledge system I am familiar with this process of secrecy and deeper meaning. Unlike the Indigenous Knowledge system, Tibetan Buddhism has a rich textual tradition. But it has also kept alive a strong oral tradition, of knowledge passed by a Buddhist master who is recognised as having not only learning but also spiritual realisation, to his/her student. The teachers talk of the outer, inner and secret meaning, and in terms of the provisional versus the absolute meaning gained through realisation.
